To provide an edible ingredient having an exceptional effect for enhancing umami. An umami-enhancing composition having a carotenoid degradation product as an active ingredient. The umami-enhancing composition can be formulated through a manufacturing method that includes a step for adding a carotenoid to an edible oil and fat, and a step for degrading the carotenoid in the edible oil and fat. The carotenoid degradation product is preferably a degradation product of one or more selected from the group consisting of carotenes and xanthophylls. The umami-enhancing composition is optimally used as a food-product ingredient, etc., for manufacturing a seasoning or extract or for enhancing the umami of a food product.
